A new report published by a Rutgers-Camden professor on Wednesday states there are more areas of concentrated poverty in the United States than have been previously recorded, with small to mid-sized cities showing the biggest increase in impoverished neighborhoods.

According to Paul Jargowsky a public policy professor and director of the Center for Urban Research and Education, more than 11 million Americans — about 4 percent of the population — now live in neighborhoods where two out of every five households live below the poverty line.
